[" (d) "lf sin A+sin^(2)A=1" then show that "cos^(2)A+cos^(4)],[=1]

If sin A+sin^(2)A=1, then show that cos^(2)A+cos^(4)A=1

sin A+sin^(2)A=1 then find cos^(2)A+cos^(4)A=

If sin x + sin^2 x = 1 , show that : cos^4 x+ cos^2 x=1 .

If sin A+sin^(2)A=1, then the value of cos^(2)A+cos^(4)A is 2(b)1(c)-2(d)0

If sin A + sin^(2)A + sin^(3)A =1 , then , prove that cos^(6) A - 4 cos^(4) A + 8 cos^(2) A =4 .

It (cos^4A)/(cos^2B)+(sin^4A)/(sin^2B)=1 then show that (cos^4B)/(cos^2A)+(sin^4B)/(sin^2A)=1

If (frac(cos^4 B)(cos^2 A))+(frac(sin^4 B)(sin^2 A))=1 then show that, (frac(cos^4 A)(cos^2 B))+(frac(sin^4 B)(sin^2 A))=1

If (cos ^ (4) x) / (cos ^ (2) y) + (sin ^ (4) x) / (sin ^ (2) y) = 1 then prove that (cos ^ (4) y) / (cos ^ (2) x) + (sin ^ (4) y) / (sin ^ (2) x) = 1

If sin A+sin^(2)A+sin^(3)A=1, then find the value of cos^(6)A-4cos^(4)A+8cos^(2)A

If "sin" x + "sin"^(2) x = 1 show that: cos^(4)x + cos^(2)x = 1 (ii) If "sin" x + cos x =sqrt(2) cos x show that: sqrt2 sin x = cos x - sin x
